When making changes to netflow profile (changing between v9 and v5), mcpd CPU usage on one core goes high, and a core file is written. The problem occurs only when modifying root netflow profile that is referenced by a child netflow. Modifying the root netflow profile works as expected when it is not being referred to by any child netflow. When the issue occurs, mcpd gets into a loop and hangs there for a long time.
The config changes appear to have been made. However, mcpd processes the config and stops responding. While mcpd restarts, there is no traffic management functionality (e.g., cannot retrieve or update system status, cannot reconfigure system, other daemons are not functional).
